This patch adds YAML schema for DT bindings of few AHUB modules. These devices will be registered as ASoC components and bindings will be used on Tegra210 and later chips. The bindings for below mentioned modules are added: * SFC (Sampling Frequency Converter) * MVC (Master Volume Control) * AMX (Audio Multiplexer) * ADX (Audio Demultiplexer) * Mixer Signed-off-by: Sameer Pujar <spujar@nvidia.com> Cc: Rob Herring <robh+dt@kernel.org> Reviewed-by: Rob Herring <robh@kernel.org> Link: https://lore.kernel.org/r/1631551342-25469-5-git-send-email-spujar@nvidia.com Signed-off-by: Mark Brown <broonie@kernel.org>

Mixer has ten inputs and five outputs. Accordingly ACIF (Audio
|
|
Client Interfaces) port nodes are defined to represent Mixer
|
|
inputs (port 0 to 9) and outputs (port 10 to 14). These are
|
|
connected to corresponding ports on AHUB (Audio Hub).
